| Cause | Symptoms | Findings |
|---|
| Lacrimal duct stenosis Lacrimal Duct Stenosis | - Recurring conjunctivitis
- Abundant tearing and purulent discharge
| - Tearing and purulent discharge from the eye
- In lower lacrimal duct stenosis, pressing on the lacrimal sac produces pus or mucus from the lacrimal punctum
|
| Eyelid turned inward (entropium) Entropion and Ectropion | - Pain
- Redness
- Foreign body sensation
- Watering
- Recurring conjunctivitis
| - Eyelashes touching the eye
- Punctate keratitis or ulceration of the cornea (best seen by fluorescein staining under blue light)
- Conjunctival erythema
- As the patient squeezes their eye shut and opens it, the eyelid may remain in a malposition turned inward.
|
| Eyelid margin turning outward (ectropium) Entropion and Ectropion | | - Eyelid turning outward
- Conjunctival erythema
- Punctate keratitis or ulceration of the cornea
|
| Dry eye syndrome Dry Eye Syndrome | - A dry, foreign body or gritty sensation
- Itching
- Watering
- Eye fatigue
- Variation of visual acuity
| - Erythema and chemosis of the conjunctiva or of eyelid margins
- Decreased fluorescence tear break-up time (FBUT)
- Fluorescein staining of the cornea and conjunctiva
|
| Blepharitis Blepharitis | - Itching
- Foreign body sensation
- Purulent discharge
- Watering
| - Rounded and erythematous eyelid margins
- Crusty eyelash roots
- Erythema and scaling of the skin
- Obstructed Meibomian glands
- Scarring and malposition of the eyelid
|
| Conjunctivitis Conjunctivitis | Bacterial inflammation
- Erythema, itching and gritty sensation in the eye
- Watering
- Gluing together of the eyelashes, particularly in the morning
Viral inflammation
- Itching, gritty sensation
- Watering
- Often concomitant upper respiratory tract infection
| Bacterial inflammation
- Conjunctival injection
- Purulent, yellowish discharge
- Subconjunctival accumulation of fluid (chemosis)
- Erythema and oedema of eyelids
Viral inflammation
- Conjunctival injection
- Watery discharge
- Erythema and oedema of eyelids
|
| Keratitis Keratitis | - Watering
- Pain
- Photophobia
- Impaired vision
| - Redness of the eyes
- In allergic form, eyelid skin affected
- In fluorescein staining, changes seen under blue light
|
| Conjunctival or corneal foreign body A Foreign Body on the Cornea | - Watering
- Redness
- Pain
- History of injury
| - Conjunctival foreign bodies may be difficult to find.
- Linear scratches on the cornea seen in fluorescein staining may reveal a foreign body underneath the upper eyelid.
